Mexico City just announced a new chatbot called XOLI to guide tourists during the FIFA World Cup. 🇲🇽 It probably cost millions of pesos to build and promote. So I asked it a simple question👇 “Where can I find the best tacos in CDMX?” It crashed. 🤦♂️



sisis, todo bien con la evolución pero de qué sirve si no entendes los bugs que te genera la ai y también le delegas el pensamiento critico a la ai.






This was my assignment as a backend and infra engineer at a startup based in Singapore the main goal was to implement a system that accepts a stream of events (here HTTP) and filters out duplicate events which were identified as a composite key we discussed around the system architecture got into few problems while building and also explained how did I solved it like for example tech stack : go, redis, psql, prometheus and grafana with html and tailwindcss done with claude >Prometheus dashboard was not showing the accurate graphs ... prometheus.yml scrapes app:8080 but Prometheus runs in Docker while the Go app runs on localhost ... the answer was simple it should be using host.docker.internal:8080 > why is our dashboard lagging ?? e.created_at.split('T')[1].split('.')[0] will crash if created_at is null or malformed meaning our given json input carried some invalid brackets







Algún día contaré la historia de mi primer trabajo con 18 años mientras estudiaba el grado superior de informática Cobrando la gran fortuna de 6€/h con turnos partidos 🤠









As a dev, which backend framework do you prefer?
